Red Button SEO Poisoning and Malware Campaign

Red Button SEO Poisoning and Malware Campaign

At the forefront of this attack is the use of a website referrer, or user-agent, which enables the cybercriminals to effectively increase their search engine ranking while keeping their malicious intentions hidden. Google and other search engine bots will be served up SEO tailored content to manipulate search results and drive traffic. This content cleverly uses a mashup of text and images scraped from various sites.

Danger lurks for users that visit these pages using Google search or other search engines. In the course of monitoring, zvelo has seen these pages deliver Rogue AV, redirect to fraudulent pharmacies, fake search pages and more.

At the time of writing, most of the sites involved in the campaign are currently hosting a Red Button flash file, as shown below. This file indicates a compromise, but clicking the red button currently does nothing malicious, but these pages serve as a placeholder for the attackers. These pages change their character depending on how they are referenced and at any time these pages could be infect the user with malware.
